Nov. 29, 1932 E. c. ROSENBERG BRUSH Filed Nov. 17. 1950 Patented Nov.29, 1932 UNITED STATES EDWIN C. ROSENBERG, OF MILWAUKEE, WISCONSIN BRUSHApplication filed November 17, 1930. Serial No. 496,052.

My invention relates to an improvement in brushes.

The object of my invention is to provide a brushwithin a case of verysmall dimen- 5 sions and provided with bristle carrying memberscollapsed within the case and extensible in the opening of the case toprovide a workable brush.

Another object of my invention is, to prom vide an actuating mechanismfor collapsible bristle carriers.

Another. object of my invention is to pro vide a case and holder forbrush bristles which will take up very little room in a suit 1 case orother package and will, when unfolded or opened up, comprise a back forthe brush in compact, solid form.

In the drawing:

Figure 1 shows my brush and case completely closed.

Figure 2 shows the same case in completely open position. 1

Figure 3 shows the brush and case partially opened.

Figure 4 shows the case almost closed.

Figure 5 shows the internal mechanism in exploded view.

Figure 6 is a section drawn on line 6-6 of Figure 5.

Like parts are designated by the same reference characters throughoutthe several views.

My improved folding or collapsible brush cluding the bristle holdingcase 10, a cover 11, and a number of bristle clips 12. The mechanicalfeatures important to my invention include a sliding hinge mechanismconnecting the case 10 and the cover 11 and a number of mechanicaldevices and elements at the opposite end of the cover as shown inincludes certain major structural parts in Figure 2 and the free end 14in Figure 1 as sumes the position shown at 14 in Figure 2. In theintermediate partially open position the respective ends of the case 10are in the position shown in Figure 3. This is accomplished through theinclusion in the side walls of the cover of slots 15 which receiveslides 16 with which bearing members 17 are integral.

It will be noted that the bearingmember 17 is eccentrically positionedwith respect to the slide 16 and thatthe aperture 18-which receives thebearing member 17 is substantially centrally positioned with respect tothe vertical dimension of the case 10. This compensates for thedifference in elevation of the case which I have found preferably whenthe brush is closed for packing or open for use. As shown in Figure 1the caseis snugly po sitioned within the margins of the cover level 7and some additional space is provided in the open brush between the case10 and the cover 11 so that a handle 19 has plenty of room between thecover and the case and comprises a brace against which thepressureduring use 5' of the brush may be exerted at one end of thebrush while the hinge construction at the other end of the brushmaintains the parts in rigid relationship. t.

From the above it will be understood that whenthe closed or folded brushdevice is to be opened the handle 19, as shown in Figure 1', will bepulled so as to hingedly remove the case 10 from the cover 11.Th6I1,WhGI1 the end 13 of the case is free from its corresponding endofthe case 11 the end 14 may be slidably moved to the other end of thecover 11 and the end 14 of the case may be pressed down into the cover,as indicated in Figure 2. The mechanism for folding or unfolding thebristle clips 12 includes slotted side members 20 at either side of thecase 10 through which a stub shaft 21 eccentric to the hinge part 17projects. Just inside the slotted side a member 20 I provide a bristleclip actuator 22 which is provided with a slotted end 23 which isengaged by the stub shaft 21 so that as the case 10 is hingedly movedwith reference to the hinge member 17 the clip actuator 22 uponthe'eccentrically mounted stud shaft 21 is caused to reciprocate in itsposition along the side wall of the side member 20. Each of the clips 12holding bristles 24 is provided with trunnions 25 receivable in holes 26provided, therefore, in the clip actuator 22. Studs 27 at either end ofthe clips 12 project between the saw teeth of the clip actuator 22 andare receivable in the slots 28 in the side member 20. A spacer tube 29receivable upon the stub shafts 21 serves to maintain the clip actuatorsin spaced relation and prevent them'from bendingupon the ends of thebristle clips. It will be noted that the tips of the saw teeth 30 areblunt and that they are of sufiicient height to slide beneath the studs27 when the clip and bristles are in a position perpendicular to thefloor of the case 10 and when the clip actuator is moved with referenceto the studs 27, the space between the saw teeth 30 of the clip 22permit the bristles and the bristle clip to assume a position parallelor nearly parallel to the bottom of the case 10. V

In operation therefore the parts described above are disposed and movedas follows:

When the case' is opened as shown in Fig ure 2 the bristle clips are inposition perpendicular to the floor and the case 10, the studs 27 aredisposed over the tops of the blunt tips of the saw teeth 20 and theactuator 22 and extend into the slots 28 in the slide members 20. Thenas the case is hingedly pulled from clip receivable in an aperture inthe actuator whereby in the movement of said actuator to cause said clipto oscillate pivotally upon said trunnions, said notched actuator actingas a cam and blunt points between said notches in the actuatorinteracting with the said studs to brace the clip in upright positionwhen the trunnion is in the end of a slot.

4. The combination with a box member and cover member, one nested withinthe other, of a hinge member on said box member provided with alaterally extended slide, the exterior member being provided with a slotto receive said slide, whereby the box member may be slidably, hingedlyinverted from one nested position to another.

5. The combination with a box member and cover member, one nestedwithinthe other, of a hinge member on said box member provided with alaterally extended slide, the exterior members. 7

the cover 11, the slides 16 hold the stub shaft 10 in fixed relation tothe cover so that the actuator 22 with its slotted end 23 embracing thestub, shaft 21 is moved longitudinally of the case so as to actuate thebristle clip 12 by movingthe trunnions 25- while the studs 27 are heldby the slots 28, thus swinging the clip 12 toward a horizontal position.

I claim:

-1. The combination with a case and a slotted cover therefor, of abristle clip mounted for oscillation in the case, a slide fitted to theslot in the-cover and a hinge in connection with said slide to supportthe case with reference to the cover,an actuator for the bristle clipmounted within the case and connected with the hinge, whereby tooscillate the clip in coordination with the movement of the 2 coverhingedly with reference to the case.

with apertures, a trunnion upon said bristle
